Toall whom it may COTNCTR.

Be it known that I, JULIUS HnNnY P rcnnnns, a citizen of the United States, and a resident of Torrington, county of liilehlield, and State of (o1niectirut, have in- 5 vented certain new and nselul Improvements in Transmission Mechanism, of which the following isa full, clear, and exact description.

This invention relates more particularly to speed changing and power transmission devices l'Onaut-oinohiles.

The primary object of the invention is'to provide a transmission mechanism for automobiles which is adapted to have a part thereof run at the same speed as the engine; which may be inclosed and carried in part by the engine fly-wheel; which is simple in operation and inexpensive to manufacture; and which has the highest speed always at the drivers command and which may be obtained immediately regardless of the speed at which the or is running and without discon- 0 neeting the usual fly-Wheel clutch or POI'lOZIlliilg any other separate and independent operation.

Another object of the invention is to provide simple and ellicient transmission means in which it is inipossible to throw into mesh two gears at the same time, and in which none of the gears revolve on their own boarings or axis when the parts are thrown in a posit-ion lor high speed. v

A further objcct ol the invention is to so arrange the transmission gears that the power will be applied-away 30.1mm the transmission shalt so as to obtain a leverage or purchase in the driving thereof.

With these and otherobjects in view, the invention will be hereinafter more particularly described with rei- Orimoe to the accompanying drawings, which forin a part'ol this specification, and will then he pointed out in the claims at the end of the description.

In the drawings-Figure 1 is a vertical section,

in elevation, of one ionn of device emhodying vontion. Fig. 2 is asoction on the line Il-ll of Fig. 1

a lar 12 which is formed on or securedto the engine shaft through the transmissionrshaft, showing one means for operatingtho high speed .lutch. Fig. 3 is' a vertical section, partly broken away, taken through the transmission shaft and showing the means for locking some of partly in elevation, showing \a. I slightly different rangomont of the transmission gears, and means for changing the speed. Fig. 5 is a vertical section through the transmission shalt showing the clutch .mechanism in elevation; and Fig. 6 is a. vertical section, partly in elevation, of a slightly different .l'orin and arrangement of the partsior changing the speedv The fly-wheel 10 may be attached to the engine shalt 11 in the usual way and may be of any desired form. As shown the fly-Wheel is provided with a. boss 11", and to this boss is secured by bolts or otherwise a flange, or soilthe gears to the-shalt. Fig. 4 iso vertical section,

, gears 21, 22, and 23 The shaft 11 may be operated in the usual manner, and said engine shaft may project slightly beyond the collar 12 so as to enter the recess inthe boss 11 of the fly-wheel to center and aline the same. In alinement with the engine shaft is a transmission shaft 14 between which and the engine shaft 11 is arranged a fibrous or other Washer 15, one end of the transmissionhhaft 14 be ing held to rotate in the fly-wheel boss ll". The flywheel 10 has a web portion 16 from which the rim l6 projects, and fitting'the rim 16 isa head or cap portion '17, which with the fly-wheel forms a casing for the transmission gears 18. The fly-Wheel thus serves as a casing to entirely incloso the transmission gears, and said gears, or a part thereof, may be so arranged' that they will serve as a,'balance and compensate for some of the weightol'thc fly-wheel proper, but it is to be understood that the transmission mechanism need not necessarily be connected with the engine or fly-Wheel shaft or formed as a part of the fly-wheel or a continuation of the engine shaft, but may be located at any suitable point, and operated from the engine shaft in any dcsirod manner; I I

The transmission gears .18, Fig. 3 have one set thereof arranged with the transmission shaft 14 as its Xlii, and two sets 19 arranged on opposite sides of the shaft 14, though instead of two sets of gears .19 there may be any suitable number. The sets of gears 19 are so arranged that they will serve to balance the fly-wheel in. it's rotary movement, and each set comprises a plurality of gears of different diameters. As shown there are fonr gears 20, 21, .22, and 23 irreach set 19, and these gears are adapted to mesh with the gears 24, 25, 26 and 27 resp'ectively, whioh latter rotate with the transmission shaft 14 as an axis. The gears of each set of planetary or revolubie gears 19 are rigidly held togethenand may be integral and the gear may he keyed or otherwise secured to the other gears so that they will always rotate in unison. These sets of gears are each provided with a bushing 29, and are held to rotate on a stnd 30 which extendsbetween theweb 16 of the fly-wheel and the cap 17, and hymen-no of the nuts 31 on opposite ends of the studs or bolts 30 of both sets of gears 19, Will not only hold the cappie'ce 17 tothe fiywheel rim, but will also secure the stud and hold the gears properly Within the 'ily-wheel. The gear 20 of 19 is the same size the gear 24 with which it is in mesh and these may be termed the driving gears,

while gears 21 and 25 indicate the gearsfor intermediate speed, the gears 22 and 26 the slow speed, and the gears 23 and 27 secure thelreverse action'oi the transmission shat; 14. The gears 25,

shaft is, and may rotate indenendent'threoi, and hold to slide in the'shaft 14 are twolie 0P2."

nected to a sleeve 33 which is adapted to be shifted lengthwise on the shaft-1 t hy a suitable lever, not

26 and 27 are loosely held on t.

These keys B2 are held in slots in the '14., and atbnefend are con- I shown, so as to fol said keys therewith. The keys 25'. have their inner ends 2H projeetingoutward beyond the periphery of the shaft it and are adapted to enter slots 34" in either of tlie gears 25. in or 27 to ltlt'k the said gears to the shaft l4. and eause said shaft to rotate with either of the gears aeeording to the position of the ends 34 of the keys. The gears 2 and 2 3 have an annular channel or groove 3:") forming a neutral point or position for the keys and whieh extends substantially one-half the thiekness of the gears to adapt. the gears 25 and 2t; to rotate independent of the shaft H when the keys are in alinement with these grooves or neutral points 35 As will be seen, if the gear 24 is held stationary, as will be presently described, and the tly-wheel rotated, the roll tary movement of the fly-wheel will cause the r voluble or planetary sets of gears 19 to be carried thereby, and during this movement the said gears will be rotated on their own axis. This independent. rotation of the sets of gears will also rotate the gears 25. 2o. 27, and the speed of the shaft l-'1 and its direi-tiou of rotation will depend upon the position of the keys 32 and which of the latter gears aid keys lot-k to the shaft. l t. The position of the keys are sat-h that they will ltltk the gear 26 to the shaft 14, and this locking of the gear to the shaft will eause said gear and shaft to rotate in unison but at. the lowest speed. If the keys are shifted so as to lttt'k the gear 25 to the shaft the next highest speed will be obtained by reason of the relative sizes of the gears, and a movement of the keys so as to loek the gear 27 to the shaft, owing to the gain by reason of the size of the gear 23 over the size of the gear 27, for example, one tooth, will eanse the gear 27 and the transmission shaft let to rotate in a re verse direetion from that of the engine shaft; and the gears 25 and 26, the relative number of teeth and the gears and their arrangement with respeet to eaeh other being varied as desired. liy arranging the sets of gears it) as shown, the power is applied to the transmission shaft M from tl tlistttttt't' so as to eause the setsof gears it) to act as levers to drive the transmission shaft, and the gears may be made to eompen for a part of the weight of the tly-wheel and to liulilum the same during its rotary movement.

For the purpose of driving the transmission shaft 1-1 at different speeds, or in a reverse direetion through the sets of gears lfl, and:the gears 2-3, 26, aml 27, I extend the hub of the gear wheel 2-] outward beyond t.he flywheeleasing and seeurelyl'astenthe gear-hub toa sleeve 36, whieh is formed as a part of the eluteh member 37. This eluteh member 37 forms a part of a suitable eluteh 2th, aml thus-aid member is held to rotate loosely on the transmission shaft 14, and is adapted to be held stationary by means of a brake-band 39 when applied to the periphery thereof. The member 37 of the ('llll.tll and the hub of the gear are held to rotate in a boss or hub of the fly-wheel easing, and between the hub aml the tly wheel easing is a suitable bushing 40. \s will be seen, when the bralua-band 25.) is applied to the periphery of the brake or tlllttll member 37, the latter and the gear 24 will be held stat ion-ary, and during the rotation of the fly-wheel around the gear 24 the latter will impart IIlUVUIDtIIL'lA) the gears 20 of the sets It), and through said gears will rotate the remaining gears 21, 22, and 23 Hill H'LNQLS 191m their own axis. This independent rory movement of the sets of gears l9 as they are (arried (i5 arottnd the shaft l-l will cause the transmission shaft. to

r tate in areverse direet ion or forward at different speeds aeeording to the posi on of the keys 32 as already explained. It is neeessary in ehanging the speed of the shaft is! to either the intermediate, slow or the reverse to not only stop and hold the member 37 of the eluteh stationary, but also to shift. the keys lengthwise of the transmission shaft. so as to engage either of the wheels 25, 26, or .7 to lot-k the same to the transmission shaft.

The highest speed of the transmission shaft. 14 may be obtained at any time while the maehine is running no matter what the position of the loeking keys may be and entirely independent of any movement of said keys. To et'feet this the eluteh 38 has a. member 41 fastened to the 'transm on shaft 14, and said rigid member has a disk-like frietion fare, and opposed to said face a movable frietion disk 12 which is slid ingly held ou the member 4| and is adapted to rotate. therewith. A disk 43 is held to the member 37 in any suitable way, and between this member or disk and the opposed fates of members 37 and -tl are arranged fibrous or other frietion disks -tt, whieh are adapted to clamp the members 37, -.t2, and 43 rigidly together when the member 42 is forced inward toward the member 4L The member =1] has a sleeve 45 adjustabl y held thereon, and on this sleeve are pivoted eluteh arms 46, the inner ends of which are earn-shaped and adapted to engage the outer surfaeeof the elamping member 42 of the clutch, and have theirother ends arranged in the path of a clutch sleeve 47 whieh is slidingly held on the transmission shaft 14. As the elnteh sleeve 47 is moved, it will engage the outer ends of the eluteh arms 46 and will foree the member 42 of the eluteh into clamping engagement with the member 42, so as to lock said members and the member 37 of the (-luteh together. This action of the eluteh will cause all the parts to rotate together with the fly-wheel or engine shaft if the keys 32 are in position to loek either of the gears 25, 26'or 27 to the shaft 14, and when said parts are so locked together they will rotate at the same speed as the engine shaft. The eluteh shown is of a common type. and it is not partieularly elaimed herein as the same may be of any suitable or desired eonstruetion. By the means shown, the highest speed or that eorresponding to the speed of the engine shaft. may be obtained entirely independent. of the movement or the position of the keys 32 so long as the latter are in position to loek either of the gears 25, 2(5 or 27 to the transmission shaft. I When the eluteh 38 is operated to cause the transmission shaft to rotate at. the highest speed, it is neees sary to release the brakwband 35) from the member 37 of the eluteh, in order that all the parts may rotate together. As shown, the eluteh sleeve 17 is engaged by the forked end of the lever 48 which is pivoted at 48" to the end 49 of a braeket 50, said braeket being of any suitable form, and arranged so that. it may be bolted' or otherwise seeured to a part. of the vehiele frame. This lever '18 is eomieeted at; its upper end to a. rod 51 or other operating means, and to the lever 48 is eonneeted a link 52. This link 52 has its other end eonneeted to a (am-bar 5i and this eambar is held to slide in the angular portion of the braeket. 50. The ('ambar 53 has its (ram arranged in the path of movement; of the inwardly turned end 55 of a rod 56. This rod 56 is guided in slots in the angular part. of the bracket. 50,

I and has its end arrsnged so that the movement of the camrbar by the lever 48 will force the rod 56 outward, and this outward movement of the cam-borwiil tighten the brake-band 39 around the periphery of the brake or clutch member.37 of the clutch 38, so as to hold said member stationary. A spring 57 is arranged between the outwardly bent ends 58 of the brake-band, and is intended to restore the rod 56 to its inward position when the bond is released. The band at one end thereof is held to e yielding arm or bracket 59 which is secured to the bracket 50, and this bracket 59 is adapted .to cause the brake-bond to move to a position so as not to clamp the member 37 of the clutch. As the arm 48 is moved on its' pivot 48 to throw the clutch into operation to;lock the parts together, it will release the EbndBQ from engagement with the member 37 of the clutch 38, and when the brake-band 39 is applied to the clutch member the clutch will be disen-, gagcd, so that it will be impossible for both the clutch and the bralie-bandto be applied at the same time, though it will he understood that an intermediate position of the'lever 48 will cause both brake-band and the clutch to be released. i

In Figs, 4 and 5 the construction is somewhat similar to that already described, hut'the arrangement of the gears and'thc operatirigparts lll'C somewhat differently constructed. The engine shaft 60 end ,the transmission shaft 61 may be arranged in the same relative position as shown in the other figures, and to a pertof the fly= wheel 62 may be secured a casing 63 iii-which lean ranged two sets of gears 64. These gears (34 correspond" in operation and position to the sets of gears 19 of Fig. 1 and are adaptedtorotate in unison upon bushings which are held by the studs 30 within the casing 63. The gears of the sets 64 are arranged with respect to each other slightly different from the gears of the sets 192' As shown, the gear'llfi indicates the reverse, 67 the slow; 68 theintermediate, and 69 the driving gears. These gears mesh with gears 70, 71, 72, and 73 respectively, and the gezir 73 is fastened to the transmission shaft 61 The gear '12 is held to a sleeve 74 which is secured to the member 37 of the clutch 38, the latter being substantially the same as shown in Fig. 1. The gear71 is held to a. sieevg75, and this'slecve is secured to a brske-wheel; 76, while the gear has a sleeve 77 which is secured to a brake-wheel 78. Each of the brake-wheels 3'7, ,76, and 78 are adapted to have a brake-bend 79 applied thereto by any suitable means, and independent of each other, and in case either of said brake-wheels is held stationary, it will hold the g ar. c'ifinneeted therewith also stationary, and thus I caluseen independent rotation of the sets of gears 64 on their own axis as they revolve with the fly-wheel, and this rotation will'be communicated to the gears 69 and'73, and through thelatter to the transmission shaft [61." As in the other construction, the reverse motion of the transmission shaft is obtained by the difference of size between the respective driving gears and the gears operatively connected with the transmission shaft, so that a siight gain. in the rotation. of

the sets 'of gears 64 or the reversing set will cause the shalt to move in the opposite direction to that in which the engine shaft rotates. The clutch shown is substantially the same as that preyioizsly described, andthis clul ch as well as the brake-bend may be operated in see s 1r arts innv rotnlc toi ethcr to secure tho hi host s )ocd P o h l any suitable way, and they arc so arranged that the clutch will not opcmtc to lock the parts together Willioui first relczising all of lholnuke-bonds.

Fig. 6 shows a couslriu'tion very similar lo that of Fig. i, and the illl'lll'lgvlllt'lli of ihc tmnsmissiorigears 70 is substantially identical. For the sake of clczuuo s the gears arc numbered the some as in Fig. l, and the main difi'crcncc in this construction from that ol Fig.

1 is that instead of tho sliding keys which move into engagement with the gears: 25, 26, and 27, these latter gears are secured to each oihcl and to sliding bars 80 which are connected to be moved along the transmission shaft 14 as already described. These bars 80 are held in grooves in the transmission shaft 14, and in said transmission slmi'l arc additional keys 8] along 80 u'hich the gcars 25, 2G, and 27 are adapted to slide. In .cnusiug these gears to move in unison instead of the keys, it is necessary to spread the gears of the sets 1S) iurtl cr apart so that 11 neutral position may be obinilicd.

In the position shown in Fig. 5 the mrivcuu-nt of the transmission slml't will be reverse oitlmt oi the engine shaft, and ii the gear 26 is in mesh with the gear 22 it slow speed will be obtained, and on lurthcr movement so that the gear will mesh with the gczu' 2| an interlncdiatc spocd will be ()lllzlllllil. Tho construction and arrangem nt of the clutch 38, and the means by which it is tliifown ihio locking position so that all the 7 or to release the bmkcdmnd from the clutch wheel or member 37'-'is flllllfil llll-lillly the same as shown in Figs.

1 and 2. As in Fig. l Lhc gcnr 24 is hold to roluic with the brake-member of the clutch, so that when the brake-bond applied to hold said member stationary, the gear 24 will also be bold stationery, and said goal" will cause the scts ol gczn's ill to rotate in unison and T00 impart movcmcnt to the transmission slmft l4 accordving to which gear 25, 26 or 27 is in mesh with its corresponding gears of the sols 19.

From the foregoing it will be iii-cu that simplc and efficient moans is provided whereby the power may be applied to thctransmission shaft at a point distant therefrom so tlnilntho gears may be of a small diameter, and still obtain a proper porch-use or lcvemgc to rotate the some; that simple means is provided to throw the parts into position to obtain either it forward or reverse 1 l0 1.
